METHOD OF TREATING LIQUIDS AND LIQUID-CONTAINERS.

Specification of Letters Patent.

Patented. Aug. is, 1908.

Application filed March 2, 1908. Serial No. 418,856.

To all whom it may concern:

Be it known that I, FREDERIC B. OAMORS, citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented new and useful Improvements in Methods ofTreating Li uids and Liquid-Containers, of which the fo owing is aspecification.

My invention relates to the purification of liquids and to theprevention of deposits in and the removal of old deposits from liquidcontainers, of-various descriptions, and the invention relatesparticularly to the transformation, purification and softening of saltand fresh waters and to the prevention of scales and the removal of oldscales in boilers and water containers of various descriptions in whichsuch waters are treated.

One of the objects of the invention is the provision of an economicalmethod by the practice of which matters in suspension in the water beingtreated are mechanically precipitated and salts are formed which, ingeneral, are non-soluble and non-incrusting.

Other advantageous features of the invention will be fully understoodfrom the following description and claims.

I 'use in the treatment of water, barium aluminate and sodium aluminate,either singly or in combination; the quantity required beingdeterminedby test of the water and the quantity and kind of chemicals to be decomosed. I

In t 1e treatment of salt or brackish water (sea and river water) withsodium aluminate the equations are as follows:

In the treatment of sea or brackish water with barium aluminate, theresulting equa tion is: Barium aluminate sodium chlorid sodium aluminate(soluble) +barium chlorid (soluble). This produces two soluble salts,but it will be noted that the sodium aluminate and the barium chloridwill act as nonincrusting" saltsand will form with the sulfates a bariumsulfate (insoluble) and magnesia+calcium chlorids, which chlorids willreappear sodium chlorids by the action of sodium aluminate, thus:

Barium aluminate magnesia sulfate magnesiaaluminate (insoluble) bariumsulfate (insoluble).

Barium aluminate calcium sulfate calcium aluminate (insoluble) bariumsulfate (insoluble) Barium aluminate calcium chlorid calci-- umaluminate (insoluble) +barium chlorid (soluble). Barium aluminate manesia chlorid magnesia aluminate (inso uble) +barium chlo rid (soluble).a Barium aluminate calcium bi-carbonate barium carbonate (insoluble)aluminum oxid (insoluble) calcium carbonate (insoluble) H O. Bariumaluminate magnesia bi-carbonatc ma nesia carbonate (insoluble) bariumcar onate (insoluble) aluminum oxid (insoluble) H O.

As will be readily understood from the foregoing a better result isattained by the use of barium aluminate than when sodium aluminate isemployedthat is, so far as the subsequent products remaining in solutionare concerned, but in this connection it will be manifest that theaddition of a'small, proportion'of sodium aluminate can only-conduce togood results since the sodium aluminate acts immediately on incrustingsalts which should be attacked immediately upon the introduction of: thebarium aluminate and the sodium aluminate into a water container. v

In the treatment of fresh water from various sources of sup )ly Ipreferably employ barium aluminate and sodium aluminate as an auxiliary'thereto. The barium and sodium aluminate act both chemically andmechanically since there is a double decomposition with the salts, andthe acids are saturated, and the precipitates formed, whether theycontain aluminum or aluminum products carry downward mechanically themajor portion ofter in suitable proportion to suit the chemicalconstituents of the water to be treated, and

agglomeration,

From the foregoing it will beunderstood that all products ofdecomposition are insoluble, as is desirable.

The equations following the use of sodium aluminate are as .follows, viz

Al oma c co coui Na CO +A1 O5+ CaCO -l-H O.

The aluminum oxid formed mixes with the calcium carbonate recipitatedand prevents wiiile sodium carbonate formed reacts,'in turn, on the"chloride and alkaline sufates contained in most-natural Waters, giving:

- Na C0 CaSO Na SQ, CaCO Na CO CaCl (NaCD CaCO aluminate and sodiumaluminate, either singly or in combination and either in solution orpowder form, forthepurification,

transformation and softening of sea and fresh waters and for theprevention of -scales in and the'removal of scales from boilers andwater containers of..various descriptions.

Forthe purpose of removin incrustations from water containers anaditional dosing of 20% to 30%.is generally necessary, but

when the containers. are. free from incrustsalts.

y novel method is also designed to. be used'to advantage in preventingthe'icolleotion of incrustations or other deposits in and removing oldincrustationsor other deposits from vacuum and cooking pans, single andplural eflect pans, and tanks and other sugarsyrup and molassescontainers, and in carrying'out the same I introduce into syru to bepurified or the container to be cleare of incrustations and otherdepositsaluminate of I barium andpreferably aluminate of sodium;

.and eliminating incrustations from liguid :COIitiiJIlGI'S, whlchconsists 1n the intro the aluminate of sodium serving in many cases as apowerful auxiliary to the aluminate-of barium. The aluminate of bariumand the aluminate of sodium may be mixed dry or in solution withoutinvolving departure from the scope of my invention. as claimed, though Iprefer to use the said aluminates in solutions since in such state theyare more effective for the purpose stated. I also prefer to use thealuminates in the presvence of heat especially when uick work isdesired, but it is obvious that said in redients .may be usedin the coldwithout eparture.

from the spirit of'my invention.

Experience has demonstrated that when employed in suitable doses insugar syrups, mo asses and the like aswell as in other vehicles'aluminate of barium completely changes the nature of the deposits thatmay be formed, either by heat orby concentration of thejliquids or.masses charged with salts, and assures 'said. deposits being of densepulverulent and non-adhering character and easy of removal.

Ingeneral the .aluminate of barium will suffice for the removal of thedeposits, although the aluminate of sodium is a powerful auxiliary whenthe sugar syrup, molasses or sugar in the containers contain chloridsand alkaline sulfates.

Having .described my invention, what I claim and desire to secure byLetters-Patcut, is:
